Welcome to the Strelets Forum. Please feel free to discuss any aspect of 1/72 scale plastic figures, not simply Strelets. If you have any questions about our products then we will answer them here.
I think that most collectors would buy both every time. If you can get hold of them and they are compatible in size then mixing various manufacturers generally gives a much better representation. Look at the Plasticsoldierreview web site and you can see the figures and decide for yourself.
